Car I will be purchasing - is it worth it?

Yeah, sandbags are the way to go. If you plan on getting a nice set of rims, keep the original ones that came on it. Salt eats chrome up really bad and will "pitt" them. I dont drive my stang in the winter I have a Blazer w/ 4x4 to help me haul through the shitty Chicago winters.

I haven't put new rims on it. I have thought about making SLIGHT alterations to it (a new stereo system maybe?) and maybe some new rims, but I'm not a big car guy. As long as the car is nice, comfortable, can play CDs and gets me where I need to go without any trouble, I am happy.
 
Oh without a doubt.
If there is salt on the streets, my mustang WON'T get driven.
A friend has a 2000 Mustang GT and we have the same exact rims. The dumbshit drove them through the salt and snow the whole winter.
Mine are perfect and his started shedding layers from the inside of the rim and had pot marks. He threw them away last month and bought new ones. Fucking winter sucks man.
